Compressed Air Plumbing for Shop

Look here: http://www.osha.gov/dts/hib/hib_data/hib19880520.html
Warnings from OSHA and some state agencies, including an incident where
an employee suffered a broken nose and facial cuts. Even if you are
willing to take the risk, in a commercial setting it will be an OSHA
violation with potential fine if there is an OSHA inspection.

everyone will poo poo the pvc idea, but i've had it in my shop for
decades. Sweat copper works well also. I personally wouldn't screw
(no pun intended) with the black iron. It'll rust inside and be a mess
in the filters and separators.

Steve-
Just because you have used PVC for compressed air for decades and have
not suffered a failure does not counter the scientific evidence that
PVC is not an appropriate material for delivery of compressed air.

The fact that your PVC has not failed or caused injury is merely
anecdotal.

Steve-
Sometimes you make useful contributions to news group discussions,
sometimes your ignorance knows no bounds.
This current discussion falls in the later category.
Check the date on the osha letters.
Hmmmm looks like Reagan or Bush was president.
Further, if you read the notice from the private company
PLASTICS PIPE INSTITUTE
355 LEXINGTON AVENUE, NEW YORK, N.Y.10017
212-370-7341
RECOMMENDATION B
THERMOPLASTIC PIPING
FOR THE TRANSPORT OF COMPRESSED AIR
OR OTHER COMPRESSED GASES
Adopted January 19, 1972
The Plastics Pipe Institute recommends against the use of
thermoplastic pipe to transport compressed air or other compressed
gases or the testing of such piping with compressed air or other
compressed gases in exposed above ground locations, e.g. in exposed
plant piping. It is recommended that all thermoplastic piping used to
transport compressed air or other compressed gases be buried
underground or encased in shatter-resistant materials. In designing
thermoplastic piping to transport compressed air or other compressed
gases, the strength at the operating temperature, the pressure, the
energetics, and specific failure mechanism need to be evaluated.

So govt & OSHA directives hold no sway with you........looks like it
started as a non-government initiative.
I guess next you'll be arguing against changes / updates to seismic
design code because they're based on "pencil pusher" research &
analysis?
cheers
Bob

...and ignoring gun controls.

yeah well, they say (now) not to use soft copper for NG lines and
hookups. But that's all we had for almost a century. Also, ALL the NG
lines i pulled out of my 140 year old house were galvanized. They say
don't do that either. Hmmmmm.... real world, or pencil pusher???

Dave, i don't know what's up your ass, but i just try to go through life
without interference from other people. I don't get in their business
and don't expect them to get into mine. Everyone seems to be uptight
about something and always going off about nothing. So, if you have a
problem with me then filter me out. And thanks for calling me names.
It's real grown up of you. Don't bother to reply, i've already filtered
you out.

Wow! Pot and kettle thing all over.
Two trolls duke it out.

Yeah and a few days ago I posted an OT concern about the increasing
number of labeled and unlabeled off topic posts (including troll
materiel); and as expected got criticized. But the fact is, I have
been hanging out and contributing to this group for 10-15 years and
had it has been a good experience. But the increasing number of off
topic material (excluding spam) that appears to be coming for
subscribers is increasing rapidly. If it continues rec.woodworking
will become a useless wasteland just like one of our RV groups and
others. The increasing amount of venomous name calling also directly
follows the path that (
http://groups.google.com/group/rec.outdoors.rv-travel/topics?lnk=srg
) took. When I looked at rec.outdoors,rv. travel at the time of this
post there were 28 items on the subject list and one was on topic.
There is also a very large amount of fighting, name calling and
profanity on that site.
What this group needs to understand is that many, maybe most, of us
are woodworkers who spend time working in the shop, spending time with
families, etc. We do not spend large amounts of time sitting in front
of the keyboard plotting filtering strategies to protect us from the
crap that shows up in these groups. When using a group becomes too
difficult we just quit using it.
You won't miss me but as other folks fade away, as they have with
other groups, you will miss the knowledge and resources these people
provide.

Unfortunate but, some pride themselves with destroying groups and
Usenet by infiltrating the group and constantly raising the grain of
the types with the 20 grit personalities. Sometimes this takes a few
sockpuppets and that is done on a professional calibre. I have seen
too many groups bite the dust this way. This group has surprisingly
survived a tonne of this BS.
One has to wonder that some editorialize so well, with so much time
spent here, actually do any woodworking, at all.

Yeah but maintaining the site's integrity is easy:
1 - Don't post off topic
2 - If you are compelled to post off-topic, include "OT" in your
subject line.
Don't get me wrong. There is nothing wrong with occasional jokes or
good-intent banter. That is what builds camaraderie among us. But
when a group gets recognized as tolerant of BS, the spammers, trolls
and others flock like geese.
We are on the verge of becoming a sanctuary.

You, and you and me just violated those rules....LOL
